AF10043 Mass Air Flow Sensor

Quedó bastante bien en mi proyecto, swap LS

I replaced the MAF sensor on my vehicle after dealing with a rough idle and hesitation that cleaning the old sensor just wasn’t fixing anymore. I went with the Delphi AF10043 since Delphi is an OEM supplier, and I’m glad I did. Install was straightforward. Unplug the connector, swap the sensor, and that was it. No relearn procedure needed in my case and the check engine light cleared immediately after a short drive. The difference was noticeable right away. Idle smoothed out, throttle response felt normal again, and the hesitation on acceleration is gone. Fuel mileage even seems a little better, though it’s still early to say for sure. Build quality looks solid and matches the original sensor that came out. Fit was exact and the connector snapped in tight with no play. It didn’t feel like a cheap aftermarket part, which was important to me since MAF sensors can be hit or miss. I’ve had it installed for a few weeks now with no issues, no warning lights, and no weird drivability problems. If your symptoms point to a failing MAF, this is a solid replacement and cheaper than dealer pricing. Wouldn’t hesitate to buy it again.

2007 Sierra 1500 Classic. Replacing the MAF fixed a 4 month old issue that didn't have any fault codes, but was slowly driving me insane. Truck was running poor. But, it was difficult to tell unless you were the daily driver of it, which I am. Felt under powered and sluggish, and fuel milage was getting a lot worse. Truck idled fine. Fuel trims oddly looked fine, which I wouldn't have expected from a bad MAF, but I have limited mechanical knowledge. Could smell gas sometimes. Off the line, getting up to speed, it just didn't have the get-up-and-go that it used to. It would reach speeds eventually, or in the same timeframe as previously but having to give it more gas. No fault codes. Had thermal cameras underneath to check the cats. Checked fuel pressure at the rail (filter is in the tank on this year, for some idiotic reason). Cleaned throttle body. Changed plugs and wires with OEM wires and Iridium plugs. Took the transmission pan down to inspect what we could, but also to change the filter and fluid. Without a code, was just wasting money on possibilities and shotgunning parts and tests at it. Finally, the new MAF fixed it. First shake down run after install the gas mileage was wonky, but better than it had been in months. By a lot. By the end of a 30 minute drive, whatever relearning (if any) had to be done, seemed to be done, as fuel mileage locked right into where it should be. Just relieved. As far as DIY jobs go, this is one anybody, regardless of their mechanical skills, can easily do quickly in their driveway.
